My drivers side window is getting a bit loose compared to the passenger side. I began to notice this while in the car and shutting the door as the window beagn to make noise slightly flapping against the rear window seal. Is this something I can tighten or is it a complex affair requiring another trip the the dealer?
It seems as if the auto window drop when the door is first opened is not very quick an this may be the culprit causing the window to develop extra play by rubbing against the top frame seal.

 

I imagine you need to go to the dealer and have one of the techs look at it. I doubt you can fix it yourself

 

Took my dealer five minutes to fix -- mine wasn't as loos as you describe, rather water was leaking inside the door. Same resolution -- tighten the window.
